OH3 doesn't start anymore

After completing my exec bindings I started to set up other things as items. Also I updated mosquitto.
But then suddenly OH stopped and I wasn’t able to start it anymore the last 2 days.
My OH runs on Synology (Java 11), I now also have updated the memory to 8 GB RAM.

On the web client I see: no connection.
And sometimes:

Problem accessing /start/index. Reason: Not Found

So I watched the logs. In openhab.log I find:

"Could not create rrd4j database file '/volume1/@appstore/openHAB/userdata/persistence/rrd4j/HamaIR40BT_Power.rrd': Invalid file header. File [/volume1/public/openHAB/userdata/persistence/rrd4j/HamaIR40BT_Power.rrd] is not a RRD4J RRD file"

So I deleted these two files but they were always restored. How can I change that?

AFAIK this is the openHAB 2 entry, for openHAB 3 it is just


Yes, you’re absolutely right! Strange, this is the link in Synology.
It’s working! :grinning:
But before I also tried: http://ip:port and nothing happened.
And the service always stopped fast. But now it runs.
But I also have changed the rights of the file above. Because the rights were different and openhab wasn’t allowed to execute.

One more question:
This HamaIR40BT resulted to the problem above.
But always when I link its channels to a model there’s an error and OH stops.
So maybe it’s not compatible?
